    • The present invention relates to the field of fermentation technology. In particular the invention relates to fermentation processes for the production of a first and a second fermentation product by a single production organism wherein the first product is in a more reduced state than the substrate and the second fermentation product is in a more oxidised state than the substrate yet in less oxidised state than the final oxidation product CO 2 , such that the concurrent synthesis of the first and second product in the organism allows recycling of reducing power and can be performed under (partially) anaerobic conditions. The invention further relates to processes in which the first fermentation product is weak alkaline compound and the second fermentation product is a weak acidic compound. In such instances both products may be produced by a single organism in a single fermenter or each the first and second product may be produced by two different organisms that are co-fermented. Co-fermentation may be performed in two separate fermenters that are connected through micro-sieves that allow circulation of soluble medium components between the two fermenters but prevent circulation of the production organisms' cells. The invention also relates to such processes in which the first and second fermentation products are capable of forming a(n) (insoluble) complex or salt.
    • 本发明涉及发酵技术领域。 特别地,本发明涉及用于通过单一生产生物制备第一和第二发酵产物的发酵方法,其中第一产物处于比底物更低的状态,并且第二发酵产物处于比 底物,而不是最终氧化产物CO 2 2的氧化态较少,使得生物体中第一和第二产物的同时合成允许再循环还原能力并且可以在(部分)厌氧条件下进行 。 本发明还涉及第一发酵产物是弱碱性化合物和第二发酵产物是弱酸性化合物的方法。 在这种情况下,两种产品可以由单一发酵罐中的单一生物体产生,或者每种第一和第二产物可以由共同发酵的两种不同生物体产生。 共发酵可以在通过微筛连接的两个分开的发酵罐中进行,这些发酵罐允许两个发酵罐之间的可溶介质组分循环,但是防止生物生物细胞的循环。 本发明还涉及这样的方法,其中第一和第二发酵产物能够形成(n)(不溶性)络合物或盐。
